Xaiv txoj caiqhov lojthiabbeam kaumrau koj LED downlights yog qhov tseem ceeb rau kev ua tiav cov teeb pom kev zoo zoo. Cov lus qhia no suav nrog qhov ntev ntawm tus qauv, lub kaum ntse ntse, thiab yuav ua li cas xaiv qhov kev xaiv zoo tshaj plaws rau qhov chaw sib txawv.
1. LED Downlight Sizes (Diameter & Cutout Dimensions)
Downlightsyog categorized los ntawm lawvvaj tse txoj kab uas hla(tag nrho fixture loj) thiabcutout loj(qhov xav tau rau kev teeb tsa).
Qhov ntau thiab tsawg (Inches & millimeters)
| Loj (Inches) | Txoj kab uas hla (Inches) | Sib npaug (mm) | Zoo tshaj rau |
|---|---|---|---|
| 2-nti | 2.5" – 3" | 50-75 hli | Cov teeb pom kev zoo me me (cov txee tso saib, txee dai khaub ncaws) |
| 3-nti | 3.5" – 4" | 90-100 hli | Kev ua haujlwm teeb pom kev zoo (cov txee chav ua noj, chav dej saib iav heev) |
| 4-nti | 4.5" – 5" | 110-125 hli | General vaj tse teeb pom kev zoo (chav nyob, chav pw) |
| 5-nti | 5.5" – 6" | 140-150 hli | Cov chav loj dua (chaw noj mov, chav tsev) |
| 6-nti | 6.5" – 7" | 165-175 hli | Cov chaw lag luam (chaw ua haujlwm, khw muag khoom) |
| 8 po + | 8" – 10" | 200-250 hli | Siab - thaj chaw qab nthab (chaw tos txais, warehouses) |
Nco tseg:
Lub teeb me me (2 "-4")→ tsom, teeb pom kev zoo.
Nruab nrab (5 "-6")→ Balanced ambient & ua haujlwm teeb pom kev zoo.
Loj (6 "-8" +)→ Dav, ci ci rau qhov chaw loj.
2. Nkag siab Beam Angles
Covbeam kaumtxiav txim siab seb lub teeb kis tau los ntawm lub teeb downlight:
| Beam Angle | Teeb pom kev | Cov ntawv thov zoo tshaj plaws |
|---|---|---|
| Nqaim (10℃-30 degree) | Tight tsom teeb | Artwork, zaub txee, khw muag khoom accent teeb pom kev zoo |
| Nruab nrab (30℃-60 degree) | Kev taw qhia tab sis dav | Chav ua noj Islands, chav dej iav, chaw ua haujlwm |
| Dav (60℃-120 degree) | Broad, diffused glow | Chav nyob, chav pw, dav dav ambient teeb pom kev zoo |
| Dav dav (120℃+) | Yuav luag 360℃kev pab them nqi | Hallways, chaw ua haujlwm, chaw lag luam |
Yuav Ua Li Cas Xaiv Txoj Cai Beam Angle?
Teeb pom kev ua haujlwm (piv txwv li, chav ua noj txee) → 30℃-45 degree(focused teeb).
Ambient Teeb pom kev zoo (piv txwv li, chav nyob) → 60℃-90 degree(txawm qhov kev pab cuam).
High Ceilings (piv txwv li, chaw tos txais) → Nqaim (15℃-30 degree)tiv thaiv lub teeb poob.
3. Koj puas xav tau ntau lub teeb?
Siv qhov nosib nrug formularau txawm illumination:
Standard Ceiling (8-10 ft siab):
4-nti downlights→ Qhov chaw4-5 ft sib nrug.
6-nti downlights→ Qhov chaw5-6 ft sib nrug.
Qab nthab siab (10+ ft):
Lub kaum sab xis nqaim dua + qhov sib nrug ze dua rau kev pov hwm zoo dua.
Piv txwv xam:
Rau ib12 ft × 15 ft chav nyob(180 sq ft) nrog6-nti, 60℃downlights:
Qhov sib nrug pom zoo:~ 5 ft sib nrug →6 downlights(2 kab ntawm 3).
4. Xim Kub (CCT) & Brightness (Lumens)
2700K–3000K→ Sov dawb (cozy, tsev nyob).
3500K–4000K→ Nruab nrab dawb (chaw ua haujlwm, chav ua noj).
5000K–6500K→ Txias dawb (chaw nres tsheb, khw muag khoom).
Brightness Guide:
Cov chaw ua haujlwm (chaw ua noj, chav dej) → 500-800 lumens ib downlight.
General ambient teeb pom kev zoo → 300-500 lumens ib downlight.
5. Recessed vs. Nto-Mounted: Kev txiav txim siab loj
Recessed Downlights→ Yuav tsum tau lub qab nthab kab noj hniav (xyuas cutout loj).
Nto-Mounted Downlights→ Tsis xav tau kab noj hniav, tab sis protrude me ntsis.
6. Cov lus qhia Pro rau kev teeb pom kev zoo meej
✔ Txheej Teeb pom kev zoo- Muab cov kab nqaim & dav dav rau qhov tob.
✔ Dimmable LEDs- Kho qhov ci ci rau lub teeb pom kev zoo.
✔ Tsis txhob Glare- Siv baffle-trim los yog sib sib zog nqus-recessed fixtures.
✔ IC -Rated (Insulation Contact)- Muaj kev nyab xeeb rau insulated qab nthab.
Kev Pom Zoo Kawg
Chav Nyob Hauv Tsev: 4 "-5" downlights, 60℃-90℃beam, 2700K-3000K.
Chav Ua Haujlwm Teeb Pom Kev: 3 "-4" downlights, 30℃-45℃beam, 3000K-4000K.
Commercial Spaces: 6 "-8" downlights, 90℃-120℃beam, 4000K-5000K.
